SASH-WEIGHT.

SPECIFICATION forming part of Letters Patent No. 369.952, datedSeptember 13, 1887.

No model.)

To all whom it may concern.-

Be it known that I, LORENZO O. MATTEsoN, a citizen of the UnitedStates,residing at WVatertown, in the county of J efi'erson and State ofNew York, have invented certain new and useful Improvements inSash-Balances; and I do declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, and to the letters and figuresof reference marked thereon, which form a part of this specification.

Figure 1 is a side elevation of asash-weight embodying my invention.Fig. 2 is an inner side elevation of one of the weight-sections. Fig. 3is a transverse section of the same sashweight, and Fig. 4 is an endview of the same. Fig. 5 is an edge View of a modified form ofsash-weight, and Fig. 6 is an end view thereof. Fig. 7 is a detailsection showing a portion of the sash-weight and the pulley, andillustrating the method of journaling the pulley in the Weight.

My invention relates to sash-balances.

The object of my improvement is to provide a sash-weight carrying apulley over which the sash-cord passes, and which is capable of beinginserted through the ordinary pocket in window-frames which are providedwith sashbalances.

A further object is to make the weight in two parts, so as to inclosethe sash-cord pulley within, whereby certain advantages accrue, all ofwhich will be fully described in detail, and the points of novelty thenset forth in the claim.

In the drawings, a representsasash-weight, made in two parts, I) and c.

d is a pulley inclosed within the sash-weight.

e is a bolt which holds the two parts together.

f f are lugs or spurs formed on the half-section 0 of the weight, and gis a corresponding depression formed on half I). They interlock when thetwo halves are placed together and bolted, and prevent any displacementof the sections.

it is the sashcord.

z t are studs or short journals, upon which the pulley d turns.

76 is the opening within the weight within which the pulley d turns.

2 Z are openings leading from the space It on either side through thetop of the weight, and through which the sash-cord it passes.

on isthat part of the casting. immediately above the opening k andbetween the openings Z Z.

The two sections 1) c of the weight may be of equal size, dividing theweight through the center, as shown in Figs. 1, 2, 3, and 4, or thecontacting faces of the two halves may be cut in a diagonal line throughthe weight, as shown in the end view, Fig. 6, and edge View, Fig. 5, orin any other known way whereby access may be had to the opening k toremove the pulley d.

The pulley d may have comically-shaped cavities, within which the studsi 2' enter, Fig. 8; or pulley d may have the projections or studs i castupon it, as shown in Fig. 7, anda bearing made for them in the sectionsb c.

The bolt e and the opening through the weight which receives it may beof any known construction.

There may be more or less number of lugs f and recesses y, if desirable,and they may be placed on other parts of the weight-sections.

The openings Z, through whichthe sash-cord passes, may be of differentshapes. Figs. 4 and 6 illustrate two forms.

My improved sash-weight is designed more particularly in connection withthat class of sash-balances which employ a single cord on either side tobalance both sashes.

To apply my weight to the sash-cord, I first remove the bolt or key 6and take apart the two sections 1) and c. The pulley d is then taken outand a loop of the sashcord h placed within the openings Z and receptaclek, the pulley replaced, and the two sections then rebolted together.

In my improved sash-weight, made in two parts and of the relative widthand thickness shown, I am enabled to quickly adjust it upon the cord andinsert it through the usually shaped pocket made in window-frames.

Having described my invention, what I claim as new, and desire to secureby Letters In testimony whereof I affix my signature in Patent,ispresence of two witnesses.
